RESUMEN
This study described 17 cases of children admitted to the Bambino Gesù Children's Hospital with acute hepatitis of unknown origin between mid-April and November 2022. Following the World Health Organization's working case definition of probable cases, 17 children, with a median age of 2.1 years (interquartile range: 1.0-7.1), presenting with acute hepatitis non-AE, with serum transaminase >500 IU/L, were included in the study. A pre-specified set of microbiological tests was performed on different biological specimens for all pediatric patients. All patients resulted negative for the common hepatotropic viruses. The most common pathogen detected in blood specimens was human-herpes-virus-7 (52.9%). Adenovirus was detected more frequently in stool specimens (62.5%) than in respiratory (20.0%) or blood samples (17.6%). Regarding Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, one child tested positive two days after admission, while antibodies against spike and nucleoprotein were present in 82.3% of patients. A co-pathogen detection was observed in 94.1% of children. Overall, 16 children recovered without clinical complications, while one patient required liver transplantation. In these cases of acute hepatitis of unknown origin, adenovirus was mainly detected in stool samples. A co-pathogen detection was also frequently observed, suggesting that the etiology of this acute hepatitis is most probably multifactorial.
RESUMEN
BACKGROUND: Several optimized search strategies have been developed in Medicine, and more recently in Occupational Medicine. The aim of this study was to identify efficient PubMed search strategies to retrieve articles regarding putative occupational determinants of agricultural workers' diseases. METHODS: We selected the Medical Subjects Heading (MeSH) term agricultural workers' diseases and six MeSH terms describing farm work (agriculture, agrochemicals NOT pesticides, animal husbandry, pesticides, rural health, rural population) alongside 61 other promising terms. We estimated proportions of articles containing potentially pertinent information regarding occupational etiology to formulate two search strategies (one "more specific," one "more sensitive"). We applied these strategies to retrieve information on the possible occupational etiology among agricultural workers of kidney cancer, knee osteoarthritis, and multiple sclerosis. We evaluated the number of needed to read (NNR) abstracts to identify one potentially pertinent article in the context of these pathologies. RESULTS: The "more specific" search string was based on the combination of terms that yielded the highest proportion (40%) of potentially pertinent abstracts. The "more sensitive" string was based on use of broader search fields and additional coverage provided by other search terms under study. Using the "more specific" string, the NNR to find one potentially pertinent article were: 1.1 for kidney cancer; 1.4 for knee osteoarthritis; 1.2 for multiple sclerosis. Using the sensitive strategy, the NNR were 1.4, 3.6, and 6.3, respectively. CONCLUSION: The proposed strings could help health care professionals explore putative occupational etiology for agricultural workers' diseases (even if not generally thought to be work related).

PURPOSE: This study aims to report on catathrenia occurring in narcolepsy with cataplexy (NC) patients under sodium oxybate (SO) treatment. Catathrenia is a parasomnia characterized by groaning and an abnormal respiratory pattern during sleep. METHODS: Fifty-one patients with NC and starting SO therapy underwent a baseline overnight polysomnography (PSG) to detect any sleep-related breathing disorders (SRBD). To avoid risks due to a possible central respiratory control depression by SO, all patients with concomitant obstructive sleep apnea (OSA) were treated with a nasal continuous positive airway pressure (nCPAP) device. After 2 months of treatment with SO, all patients underwent a follow-up overnight PSG to investigate possible newly occurring SRBD. They also underwent a semi-structured clinical interview to monitor other potential SO side effects. RESULTS: At baseline, four out of 51 patients showed simple snoring, and eight, mild to severe OSA. After a titration PSG night, patients with OSA received a nCPAP device. After 2 months of SO treatment, 28 patients (54.9%) showed SO-related side effects, including SRBD in 11 (21.6%). The follow-up PSG showed a respiratory pattern characteristic of catathrenia in seven patients (13.7%) as a newly observed and possibly benign SO side effect, and ruled out a worsening of OSA. CONCLUSIONS: Catathrenia should be considered a possible side effect in NC patients under SO treatment and should be accurately identified to prevent unnecessary SO withdrawal.

Italy was the first country in Europe to face the coronavirus pandemic. The aim of the study was to analyze healthcare workers' (HCWs) level of information, practice, and risk perception towards COVID-19. We set up a cross-sectional study through SurveyMonkey® and distributed the link through Facebook and Whatsapp closed groups. The research instrument was a 31 items questionnaire distributed using Facebook and Whatsapp. It was conducted in Italy from February to May 2020. The study participants were general practitioners, pediatricians and other health professionals. A total of 958 participants were included: 320 (33.4%) general practitioners, 248 (25.9%) pediatricians and 390 (40.7%) other health professionals. The highest response rate was from Northern Italy (48.1%), followed by Central Italy (29.9%) and Southern Italy (22.0%). Less than a half (46%) of respondents felt they had a good level of information of COVID-19 case definition and of national prevention guidelines. Respondents reported to have changed their clinical practice; particularly, they increased the use of masks (87.1%, p < 0.001), disinfection and sanitization of doctors' offices (75.8%, p < 0.001), the use of protective glasses (71.2%, p < 0.001), alcoholic hand solution (71.2%, p < 0.001), and hand washing (31.8%, p = 0.028). HCWs are at high risk of infection; less than a half of them felt adequately prepared to face COVID-19 pandemic, so they need extensive information and awareness of the disease to take adequate precautionary measures, and they are crucial to disseminate good practices.

BACKGROUND: In Italy, the response to coronavirus disease 2019 (COVID-19) pandemic upgraded from social distancing on February 23, 2020, to national lockdown on March 11, 2020. We described how the pandemic affected a tertiary care children hospital with a dedicated COVID-19 regional center. METHODS: We analyzed the characteristics of emergency department (ED) visits, urgent hospitalizations and severe acute respiratory syndrome (SARS)-COV-2 reverse transcription-polymerase chain reaction testing, and COVID-19 patients across 3 response phases: before the first Italian case, before national lockdown and during lockdown. RESULTS: ED visits decreased from a daily mean of 239.1 before the first COVID-19 Italian case, to 79.6 during lockdown; urgent hospitalizations decreased from 30.6 to 21.2. As of April 20, 2020, 1970 persons were tested for SARS-CoV-2 reverse transcription-polymerase chain reaction and 2.6% were positive. Positive rates were 1.2% in the ED, 21.1% in the COVID center and 0.5% in other wards. The median age of COVID-19 patients (N = 33) was 6.7 years, 27% had coexisting conditions and 79% were related to family clusters. CONCLUSIONS: The pandemic strongly impacted on the use of hospital services, with a 67% reduction in ED visits and a 31% reduction in urgent hospitalizations. Separating the flows of suspected patients from all other patients, and centralization of suspected and confirmed cases in the COVID center enabled to control the risk of nosocomial SARS-CoV-2 transmission. Delay in hospital use for urgent care must be avoided, and clear communication on infection prevention and control must be provided to families. Further studies are needed to assess how the reduction in hospital use affected children healthcare needs during the pandemic.

BACKGROUND: Foodborne Hepatitis A Virus (HAV) outbreaks are being recognized as an emerging public health problem in industrialized countries. In 2013 three foodborne HAV outbreaks occurred in Europe and one in USA. During the largest of the three European outbreaks, most cases occurred in Italy (>1,200 cases as of March 31, 2014). A national Task Force was established at the beginning of the outbreak by the Ministry of Health. Mixed frozen berries were early demonstrated to be the source of infection by the identity of viral sequences in patients and in food. In the present study the molecular characterization of HAV isolates from 355 Italian cases is reported. METHODS: Molecular characterization was carried out by PCR/sequencing (VP1/2A region), comparison with reference strains and phylogenetic analysis. RESULTS: A unique strain was responsible for most characterized cases (235/355, 66.1%). Molecular data had a key role in tracing this outbreak, allowing 110 out of the 235 outbreak cases (46.8%) to be recognized in absence of any other link. The data also showed background circulation of further unrelated strains, both autochthonous and travel related, whose sequence comparison highlighted minor outbreaks and small clusters, most of them unrecognized on the basis of epidemiological data. Phylogenetic analysis showed most isolates from travel related cases clustering with reference strains originating from the same geographical area of travel. CONCLUSIONS: In conclusion, the study documents, in a real outbreak context, the crucial role of molecular analysis in investigating an old but re-emerging pathogen. Improving the molecular knowledge of HAV strains, both autochthonous and circulating in countries from which potentially contaminated foods are imported, will become increasingly important to control outbreaks by supporting trace back activities, aiming to identify the geographical source(s) of contaminated food, as well as public health interventions.

OBJECTIVE: We carried out a systematic video-polysomnographic analysis of the number and type of motor events during REM sleep in narcolepsy-cataplexy patients with REM sleep behavior disorder (NC + RBD) but not clinical RBD (NC-RBD). METHODS: Twelve NC + RBD and 10 NC-RBD male patients underwent video-polysomnography (video-PSG). Motor events of different type and complexity (i.e., elementary and complex movements and vocalizations) occurring during REM sleep were visually assessed, and indices of their frequency per hour of REM sleep were calculated. Subsequently, the index values were compared in NC + RBD versus NC-RBD patients. RESULTS: Typical RBD behaviors observed in five NC + RBD patients were not included in any type of motor events. No objective conventional sleep parameter, including visual analysis of chin electromyographic (EMG) activity, significantly differed between the two groups of NC patients. NC + RBD patients showed higher occurrence of elementary movements (p = 0.034) during REM sleep compared with NC-RBD patients, but the occurrence of complex movements did not differ significantly. CONCLUSIONS: Video-analysis of motor events during REM sleep may improve the diagnosis of RBD in NC. RBD in NC patients is mainly characterized by elementary rather than complex movements, consistent with the view that RBD with NC patients displays a distinct phenotype with respect to other RBD patients.
